Subject: Question about IBM 6611 Router

I have a question about a potential problem with the 6611 implementation.

According to the RFC, the 6611 always transmits Test COMMAND on the DLC
interface, never Test RESPONSE. The RFC indicates that a Test RESPONSE must
be received on the DLC interface (DLC_RESOLVE_R) to cause a transition from
RESOLVE PENDING to CIRCUIT PENDING. No exception is specified for the 6611.

Dosen't this present a problem when two 6611 Routers on different 
(bridged) rings send Test COMMAND to each other on the DLC interface.
Both sides can become 'stuck' in RESOLVE PENDING STATE while each one is
waiting to receive TEST RESPONSE (DLC_RESOLVE_R) from the other.

What is the reason that the 6611 does not behave according to the FSM tables
specified in the RFC?
